This commit introduces a new feature that allows you to configure the application to run on startup.
- A "Run on Startup" checkbox has been added to the system tray menu.
- The application now uses a `config.json` file to store settings, including the "run on startup" state.
- On Windows, the application adds/removes itself from the startup programs by creating/deleting a key in the Windows Registry.
This commit enhances your experience for setting a keyboard shortcut. Instead of typing the shortcut as a string, you are now prompted to press the desired key combination directly.
The `src/config.py` module has been updated to:
- Use `keyboard.read_hotkey()` to capture the key combination you press.
- Display the captured shortcut for confirmation.
- Save the shortcut only after you confirm it is correct.
This provides a more intuitive and less error-prone way for you to configure your preferred shortcut.
